The radiographic and ultrasonographic evaluation of enteric duplication cysts.

The pattern of diagnostic evaluation of seven children with duplication cysts of the gastrointestinal tract (two with bronchopulmonary foregut malformations and five with mid or hindgut duplications) is presented. Each child had plain radiographs followed by ultrasonic scans and appropriate confirmatory radiographic studies with contrast. Scans showed a well defined cystic mass in each case. Radiographs were able to identify more precisely the site of origin of the duplication cyst.
